Few days ago a package from UK got delivered. In there a clean Pentax MX. I still own several film cameras, but never managed to get hands on MX which was a dream camera for me at the time, too expensive to justify the purchase.
Loaded a roll of 400 Fujifilm in it and fired first frames with it. Experience so familiar to me from the old days, yet so far away from features, performance and handling available today with modern cameras. Yet fun.

Be weary of the RX. Near the end of the film days on the contax thread there was an issue with the RX view finder. Some part was organic in nature and had a limited life (at least I think that was the RX) and is basically non-fixable today.

I had one for a while - nice camera - but I prefer the Aria which was more similar to my old OM-1.

Anyway I really liked the system - and didn't keep the RX long - maybe a year. While it is small compared to AX/RTS; it is still much larger than I was used to and i kept using the Aria....
